Abstract

The utility model discloses a hectometer timing system which comprises a starting gun, a photoelectric bijection switch, a singlechip and a timer, wherein the starting gun comprises a remote control switch which is used for transmitting a timing signal; the singlechip is used for receiving the timing signal output from the starting gun, and used for outputting a control signal to start the photoelectric bijection switch and the timer; the photoelectric bijection switch is used for outputting a timing stopping signal to the timer. The hectometer timing system disclosed by the utility model is low in cost, precise in timing and convenient to popularize in schools.

Description

Hundred meters timekeeping systems

Technical field

The utility model relates to electronic technology field, particularly a kind of timekeeping system.

Background technology

Hundred meters test timekeeping systems in the Modern Physical Education contest, the manual time-keeping error is subject to various factors, and accuracy is comparatively low.Though the high-speed camera timing adopted in large-scale sports tournament can reach the timing effect very accurate stage, high-speed camera is expensive, is not suitable on a large scale and promotes.

The utility model content

The utility model proposes a kind of hundred meters timekeeping systems, solved existing artificial hundred meters problems that timing precision is low.

The technical solution of the utility model is achieved in that

A kind of hundred meters timekeeping systems comprise: send out number rifle, photoelectricity correlation switch, single-chip microcomputer and timer; Described number rifle comprises teleswitch, sends timing signal; Described single-chip microcomputer receives sends out number timing signal of rifle output, and the output control signal starts described photoelectricity correlation switch and timer; Described photoelectricity correlation switch output timing stop signal is to timer.

Alternatively, the quantity of described photoelectricity correlation switch is many covers, with the surface level vertical distribution.

Alternatively, the quantity of described photoelectricity correlation switch is 3 covers, is separately positioned on apart from ground 0.1-0.2m, 0.4-0.6m and 1.5-1.8m place.

Alternatively, described photoelectricity correlation switch is infrared electro correlation switch.

The beneficial effects of the utility model are: cost is low, timing is accurate.

The accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The circuit control block diagram that Fig. 1 is hundred meters timekeeping systems of the utility model.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.

As shown in Figure 1, hundred meters timekeeping systems of the utility model comprise: send out number rifle 10, photoelectricity correlation switch 20, single-chip microcomputer 30 and timer 40.Send out number rifle 10 and comprise teleswitch, trigger teleswitch and send timing signal when the fluctuation spanner; Single-chip microcomputer 30 receives the timing signal of sending out 10 outputs of number rifle, the output control signal starts photoelectricity correlation switch 20 and timer 40, the signal interruption of photoelectricity correlation switch 20 when having the sportsman to break through terminal, photoelectricity correlation switch 20 output timing stop signals are to timer 40.

In order to improve the precision of timing, the quantity of photoelectricity correlation switch 20 is many covers, with the surface level vertical distribution, preferably, whether the quantity of photoelectricity correlation switch is 3 covers, is separately positioned on apart from ground 0.1-0.2m, 0.4-0.6m and 1.5-1.8m place, detect respectively foot, shank and head and breast the tape.

In above-mentioned hundred meters timekeeping systems, photoelectricity correlation switch 20 can be infrared electro correlation switch.

When rifle rings simultaneously, send out number rifle emission timing signal, timing starts, the sportsman starts 100-metre dash, and when sportsman's process runway terminal, photoelectricity correlation switch is subject to the sportsman to be stopped, form the timing stop signal and be transferred to timer, timing stops, and completes the overall process timing, and display screen shows the last effectively achievement of sportsman.

Of the present utility model hundred meters timekeeping system costs are low, and timing is accurate, conveniently in school, promote.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
